The problem with SSL is it doesn't include certificate chain to arbitrary authorities. However, there's a space for web of trust in SSL, I believe, so yeah, a new verison of SSL might be just the ticket. On 8/22/2002 at 00:02:24 +0300, Petri Helenius said:
Treat them sort of like SSL certs now. Charge an annual registrar fee per company, not per server. (Something like $100 a year) The more they have to go out of their way to get their spam server online, the more they would be deterred to do so. They're only going to want to change so many ISP's, go through SWIP and then change their legal name for the registrar so many times.
Why don´t you just start using SSL certs with SMTP ? The protocol is there, ways to get certificates are there, no need to start smoothing a square piece to make a new wheel.
